Hydraulic, Air-Actuated, 22AUH Series

• Provides a controlled intermittent liquid spray using only liquid pressure as the force for atomization.

• An internal air cylinder automatically interrupts the liquid flow at any desired frequency up to 180 cycles per minute.

• A minimum air pressure of 45 psi (3 bar) is required for the air cylinder. The nozzle operates at liquid pressures up to 600 psi (40 bar).

• Key feature overview for 22AUH:

Features and Benefits

– Same basic design as the 22AUH but equipped with an extension in a choice of lengths.

– Stainless steel valve stem extends throughout the length of the extension and the valve seat is directly behind the spray tip for instantaneous, drip-free control.

– Operates at liquid pressures up to 250 psi (17 bar).

– 1/2" (12.7 mm) diameter mounting hole and locking screw for quick installation and positioning on a mounting bar.

– Constructed of brass with nickel-plated external surfaces. Valve seat and packing are made of PTFE and the valve stem is made of stainless steel.

– A variety of flat spray, hollow cone and full cone spray tips are available.

• Key feature overview for 22AUH-SS:– Same as 22AUH but have an inlet body and cap assembly of

stainless steel.

• Key feature overview for 22AUH-SS-11024:– Same as 22AUH but has two liquid inlets that allow continuous

recirculation of the sprayed liquid between the nozzle and the liquid supply.

• Key feature overview for 22AUH-SS-14799:– Additional adjusting screw that can limit the stroke of the

shut-off needle to control response time more precisely.

– Requires minimum air pressure of 75 psi (5 bar).
